A different thought:
Currently the logic generates stubs that:
call sched_note_syscall_enter()
Perform the system call
call sched_not_syscall_leave()
These are apparently generated by tools/mksyscall.c. There are potentially
hundreds for system call stubs, but on 7 system call functions for 0 through 6
parameters. Would it make more sense to put the instrumentation in those 7
system call functions rather than in the hundreds of system call stubs?
